HKS drop in filter 09 RA
#2
I like how my turbo sounds now. Definitely I can hear the BPV making that pssstchoo sound lol also turbo spool is louder too.
I don't know how anyone could hate this filter

I've had the HKS filter since like Aug, nothing bad to say about it so far. All u guys say how much louder the BPV is and the turbo spooling, I didn't notice ANY difference between the stock filter and the HKS noise wise.

Cool. I live where the airs pretty clean all throughout the year so I guess I'll be ok even if I go past the recommended 10k before I have to switch it out.
